PREVENA™ INCISION MANAGEMENT SYSTEM DRESSINGS
The PREVENA™ Therapy System features a PREVENA™ PEEL & PLACE™ Dressing. This dressing
contains a skin interface layer that includes 0.019% ionic silver. Silver in the interface layer of the
PREVENA™ Dressing is not intended to treat infection, but to reduce bacterial colonization in the
fabric. In vitro log reduction tests, conducted without application of negative pressure, exposed
samples of the skin interface layer to a six log challenge of each of the microorganisms listed
below. Following inoculation, samples were tested for microbial counts immediately (day 0) and
after incubation at 90˚F (32˚C) in diluted nutrient broth for 1, 3, 5 and 7 days.
The log reductions from the day 0 values are provided in the table below.
